S. BROWN, THEODORE E. WEIDER- Letters Patent No. 96,221, dated October26, 1869.

IMPRovED TBEADLE-MQTIQN.

The fcherlle referred to in these Lettera Patent and making part of thesame.

improved arrangement whereby the power may be api plied by a to-and-froswinging motion of the toot.

The invention consists of a disk, or other equivaf lentdevice,lconnected to the lower end of a vibratingv-,

pendulum, 'so as to vibrate thereon, aud to which, at the top, the crankconnecting-rod is jointed', and all arranged in such a. way thatthe'lower faceot' the disk being prevented from swinging, au oscillatingmotion imparted to the axis will swing the top back and forth, so as toimpart rotary motion to the-crank, as hereinafter more fully specified.

Figure 1 represents a side elevation of my improved treadle-motiou, andl i Figure 2 is a diagram', showing the-positions ofthe differentpartsat the different stages of the movements.

Similar letters parts. e.

A is a pendulum, suspended by'a pivot-joint from the under side of thetable, or a bracket, or other support attached to the same.

B is a heavy disk, or other suitable device, suspended frolnthelower endby .a pin or bolt, C, passling through its centre of gravity, and onwhich a footboard, D, is secured.

of reference indicate corresponding This disk B is slotted or otherwisearranged at the bottom for connection to any fixed rod or stud, E, tohold it against swingingwith the pendulum.

'.lhe pitlnan-rod li top by a wristpin, aud'to the wrist-pin of thecrank G. By placing the foot on the foot-board D, and swiiiging'thependulum forward arid back, the disk 1B willbe caused, by reason ofbeing held at the bottom, to oscillate on its centre O, so as to imparta to-andfro motion to the rod F, for working the crank-shaft through thecrank G.

The diameter of the disk should be about twice the length ofthe crank,but `it may be varied, as'may be found best in practice.

It is not essenthl that the part B should be in the form otla disk, asany other shape, which will aecomplish the object by oscillating on theaxis O, and which will support the connecting-rod on one side, while theother is held from oscillating, will do as well. 'The connecting-rod maybe at the bottomand the holdingdevice at the top if preferred. u

The vertical line a, in tig. 2,-represents the position of' the'pendulumwhen the device is standing, and the lines b c,ou each side thepositions, when the crank is passing the centres, whereby it will beseen that the crank will always be 1n the best position for startingbythe action 'of the feet on the treadle, without the aid com monlyrequired in other arrangements of the hands to' turn the cranks past thecentres.

Having thus described my invention,

1 claim as new, and desire to secure by Letters Patenti,

'lhe combinationof the pendulum A, disk B, or its equivalent, pivot-boltC, treadle), connecting-rod F, and a holding-device, E, substantially asspecified."
